ABSTRACT Objective: To perform the cross-cultural adaptation of CALCULATE for Brazilian Portuguese. Method: A methodological study conducted from January to December 2021, divided into six stages: translation, synthesis, back-translation, expert committee with the application of the content validity index, pre-testing in 40 adult patients, and submission to the authors. The study took place in the intensive care units of a public tertiary teaching hospital in the interior of the state of São Paulo, Brazil. The original CALCULATE has eight risk assessment items and is stratified with a score of 0-3 (high risk) and 4-8 (very high risk). Results: After expert evaluation, the final content validity was 0.9. They suggested words and phrases that should undergo changes regarding textual equivalences, as well as definitions of acronyms and terminologies. In the pre-test, the items were assessed as suitable for understanding; only one item required additional explanation for adequacy. Conclusion: The cross-cultural adaptation of CALCULATE for Brazilian Portuguese was successfully performed, revealing a good content validity index, confirming the relevance and appropriateness of its items. CALCULATE is suitable for use in intensive care units and research and teaching centers.

Abstract Background: Chronic leg ulcers affect a large portion of the adult population and cause a significant social and economic impact, related to outpatient and hospital care, absence from work, social security expenses, and reduced quality of life. The correct diagnosis and therapeutic approach are essential for a favorable evolution. Objective: To gather the experience of Brazilian dermatologists, reviewing the specialized literature to prepare recommendations for the diagnosis and treatment of the main types of chronic leg ulcers. Methods: Seven specialists from six university centers with experience in chronic leg ulcers were appointed by the Brazilian Society of Dermatology to reach a consensus on the diagnosis and therapeutic management of these ulcers. Based on the adapted DELPHI methodology, relevant elements were considered in the diagnosis and treatment of chronic leg ulcers of the most common causes; then, the recent literature was analyzed using the best scientific evidence. Results: The following themes were defined as relevant for this consensus - the most prevalent differential etiological diagnoses of chronic leg ulcers (venous, arterial, neuropathic, and hypertensive ulcers), as well as the management of each one. It also included the topic of general principles for local management, common to chronic ulcers, regardless of the etiology. Conclusion: This consensus addressed the main etiologies of chronic leg ulcers and their management based on scientific evidence to assist dermatologists and other health professionals and benefit the greatest number of patients with this condition.

Abstract: Ulcers or wounds can be classified as acute or chronic. Their treatment involves overall assessment of the patient and choice of suitable local therapy, and the appropriate indication and use of products. Technological progress in the field of wound treatment has increased rapidly. Constant updating, with emphasis on available scientific evidence, is necessary to offer the best approaches to patients with acute and chronic wounds. A qualitative analysis of literature was conducted to identify scientific publications that update the concepts involved in local wound treatment, to present some resources that can aid the healing process and describe the different types of dressings available. This review includes wound assessment using the acronym TIME (tissue, infection/inflammation, moisture balance and edge of wound), cleaning and debridement, infection/inflammation control, exudate control, dressing types and main indications.

Objective: to describe the methodological process of cultural adaptation of the Glamorgan Scale to Brazilian Portuguese. Method: a methodological study of translation and cultural adaptation of the Glamorgan Scale, following the six stages: initial translation, synthesis of translations, back-translation, committee of experts, pre-test, and submission of the adapted version to the author for approval. The committee of experts was composed of five physicians and, during evaluation, a semantic, idiomatic, cultural and conceptual analysis was carried out. The agreement and representativeness of the items were assessed using the Content Validity Index. A minimum value of 80% agreement was considered. Results: all stages of the translation and cross-cultural adaptation process were satisfactory. In the evaluation made by the committee of experts, all items obtained an agreement greater than 80% in the first evaluation round. The pre-test stage allowed for a critical overview of the instrument, where few modifications were suggested by the participants. Conclusion: the Glamorgan Scale was translated and culturally adapted to Brazilian Portuguese. Future psychometric studies are necessary to validate the scale.

Abstract Venous ulcers are the main causes of chronic lower-limb ulcers. The healing difficulties encourage the research and development of new products in order to achieve better therapeutic results. Fibrin sealant is one of these alternatives. Besides being a validated scaffold and drug delivery system, it possesses excellent healing properties. This review covered the last 25 years of the literature and showed that the fibrin sealant is used in various clinical situations to promote the healing of different types of ulcers, especially chronic ones. These are mostly venous in origin and usually does not respond to conventional treatment. Commercially, only the homologous fibrin sealants obtained from human blood are available, which are highly efficient but very expensive. The heterologous fibrin sealant is a non-commercial experimental low-cost product and easily produced due to the abundance of raw material. The phase I/II clinical trial is already completed and showed that the product is safe and promisingly efficacious for the treatment of chronic venous ulcers. In addition, clinical proteomic strategies to assess disease prognosis have been increasingly used. By analyzing liquid samples from the wounds through proteomic strategies, it is possible to predict before treatment which ulcers will evolve favorably and which ones will be difficult to heal. This prognosis is only possible by evaluating the expression of isolated proteins in exudates and analysis using label-free strategies for shotgun. Multicentric clinical trials will be required to evaluate the efficacy of fibrin sealant to treat chronic ulcers, as well as to validate the proteomic strategies to assess prognosis.

Abstract Background The primary clinical manifestation of skin field cancerization is the presence of actinic keratoses (AKs). Current treatments for AKs related to skin field cancerization include photodynamic therapy (PDT) and colchicine. The objective of this study is to evaluate the efficacy and safety of 0.5% colchicine cream versus PDT with methyl aminolevulinate (MAL-PDT) in the treatment of skin field cancerization. Methods In a randomized controlled and open clinical trial with a blind histopathological and immunohistochemical analysis, 36 patients with up to 10 AKs on their forearms will be included from the outpatient clinic. The forearms will be randomized into two groups, clinically evaluated and biopsied for histopathology and immunohistochemistry (p53 and Ki67). One forearm will be treated with 0.5% colchicine cream for 10 days, and the other forearm will receive one session of MAL-PDT; the forearms will subsequently be reassessed clinically and histologically after 60 days (T60) of treatment. The primary endpoint will be the point of complete clearance of AKs in T60. The sample size will enable a detection in the reduction of over 10% in AK counts between the groups with power of 0.9 and an alpha of 0.05, accounting for an estimated dropout rate of 10%, resulting in 36 patients (72 forearms). All participants included in the randomized study will be part of the analysis, and the final outcomes of any dropouts will be the value of their last visit (LOCF). The statistical analysis will be performed using SPSS 22.0, and a p value

Abstract: Background: Venous ulcers represent 70% of the lower limb ulcers. They are difficult to heal, requiring a correct diagnostic and therapeutic approach. Many products have been developed to healing, such as homologous platelet gel obtained from the platelet concentrate exceeding from blood transfusion. Objective: To evaluate the safety and efficacy of homologous platelet gel in venous ulcers compared with hydrocolloid dressing. Method: A pilot randomized clinical trial in patients with venous ulcers. Randomized groups (homologous platelet gel and hydrocolloid groups) were followed for 90 days and were assessed through the evolution of ulcerated area, qualitative analysis of vascularization and adverse events. Both groups used elastic compression. Results: We included 16 participants, with a total of 21 venous ulcers. Both treatments promoted a reduction of the areas of the ulcers in 90 days (mean 69%), there was significant difference between the groups concerning the gradual reduction of the ulcers areas, favorably to the hydrocolloid (70% vs 64%; p

BACKGROUND: squamous cell carcinoma is the second most common type of skin malignancy and may evolve to regional lymph node and distant metastases. OBJECTIVE: The objective of this study was to evaluate patients with head and neck cutaneous squamous cell carcinoma to identify its clinical and histopathological characteristics, as well as the frequency of local recurrence and metastasis. METHODS: A retrospective cohort of patients with head and neck cutaneous squamous cell carcinoma. Inclusion criteria: histopathological confirmation, follow-up for longer than one year after diagnosis. Exclusion criteria: immunosuppression; lip and oral cavity squamous cell carcinoma; and non-surgical resection of the lesion. We evaluated demographic, clinical and anatomopathologic findings and explored their associations. RESULTS: Sixty-one patients with 79 tumors and followed by 4.8±3.0 years were selected. The average age was 67.1 years, and 63% of tumors had up to two centimeters. Seven tumors (8.9%) recurred and two of them had positive margins. Recurrence was associated with higher Broders' grade (p

BACKGROUND:Venous ulcers have a significant impact on patient quality of life, and constitute a worldwide public health problem. Treatment is complex, with high failure rates.OBJECTIVES:To identify clinical and therapeutic factors that influence healing of venous ulcers.METHODS:Retrospective cohort study of patients with venous ulcers. Ulcer area was measured at the first visit (T0) and after 6 months (T6) and 1 year (T12). A reduction in ulcer area of 50% or more at T6 and T12 was the outcome of interest, weighted by clinical, demographic and treatment aspects.RESULTS:Ninety-four patients were included (137 ulcers). A reduction in ulcer area of 50% or more was seen in 40.1% of patients (95%CI 31.9 to 48.4%) at T6 and 49.6% (95%CI 41.2 to 58.1%) at T12. Complete healing occurred in 16.8% (95%CI 10.5 to 23.1%) at T6 and 27% (95%CI 19.5 to 39.5%) at T12. The lowest ulcer area reductions at T6 were associated with longstanding ulcer (RR=0.95; 95%CI 0.91 to 0.98), poor adherence to compression therapy (RR=4.04; 95%CI 1.31 to 12.41), and infection episodes (RR= 0.42; 95%CI 0.23 to 0.76). At T12, lower reductions were associated with longstanding ulcer (RR=0.95; 95%CI 0.92 to 0.98), longer topical antibiotic use (RR=0.93; 95%CI 0.87 to 0.99), and systemic antibiotic use (RR=0.63; 95%CI 0.40 to 0.99).CONCLUSIONS:Longstanding ulcer, infection, poor adherence to compression therapy, and longer topical and systemic antibiotic use were independently correlated with worse healing rates.

Para avaliar fatores relacionados ao seguimento oncológico dos carcinomas basocelulares da face, foi realizada a análise de série de casos. Avaliaram-se 465 pacientes, com 834 carcinomas basocelulares de face; 3,1% apresentaram recidivas. Nos tumores incompletamente excisados, a recidiva foi 14,7% contra 2,3% dos tumores, com margens livres. Ocorreram mais na região nasal. As taxas de recorrência evidenciaram risco cumulativo. Estes achados reforçam a importância do seguimento oncológico após a cirurgia do carcinoma basocelular.To evaluate factors related to oncological follow-up of basal cell face carcinomas it was carried out the analysis of a series of cases. Four hundred sixty-five patients with 834 basal cell face carcinomas were evaluated; 3,1% presented recurrences. There was 14.7% of recurrence in incompletely excised tumors against 2.3% of the tumors with clear margins. Recurrences were more prevalent on the nose. Relapse rates showed a cumulative risk. These findings reinforce the importance of oncological follow-up after surgery of basal cell carcinoma.

Hay-Wells syndrome or AEC (Ankyloblepharon, Ectodermal dysplasia and Cleft lip and palate syndrome) is a rare ectodermal disorder. The treatment is aimed to prevent clinical complications. We describe the case of a four-month old male patient with erosions on the scalp, trunk and arms, trachyonychia, deformity of the ears, micropenis, cleft palate, decreased eyebrow and eyelash hairs, in addition to antecedents of surgical correction of ankyloblepharon. The importance of the correct diagnosis is emphasized, besides the investigation of the associated diseases, treatment of complications and genetic counseling of the parents.

Abstract Background: One of the main adverse reactions of adjuvant radiotherapy for breast cancer is radiodermatitis. Objective: To assess the incidence of radiodermatitis in women with breast cancer, identify factors associated with its severity and determine the time at which this event occurs. Methods: Prospective cohort study in 113 women with breast cancer who were evaluated before radiotherapy and at every fifth session until the end of treatment. Logistic regression and Cox proportional regression model were used for the assessment of risk factors; P values < 0.05 were considered significant. Results: The incidence rate of radiodermatitis was 98.2% and it was demonstrated that for each additional point of the Body Mass Index (BMI), the chance of occurrence of grades II to IV radiodermatitis increases by 14% (OR = 1.14 [95% CI 1.04–1.26]; p = 0.004) and statin use increases the risk of more severe skin lesions by four-fold (OR = 4.27 [95% CI 1.11–16.42]; p = 0.035). The exclusive use of hydrogel for skin hydration was an independent factor in delaying the onset of radiodermatitis (HR = 0.55 [95% CI 0.36–0.82]; p = 0.004). Study limitations: The main limitation of this study was its external validity. The identified factors should be considered for services and populations similar to those in this study. Conclusions: There was a high incidence of radiodermatitis and its severity was related to higher BMI, statin use; there was a protective effect of hydrogel use.

Abstract Background Despite the expectations regarding the effectiveness of chloroquine (CQ) and hydroxychloroquine (HCQ) for coronavirus disease (COVID-19) management, concerns about their adverse events have remained. Objectives The objective of this systematic review was to evaluate the safety of CQ and HCQ from malarial and non-malarial randomized clinical trials (RCTs). Methods The primary outcomes were the frequencies of serious adverse events (SAEs), retinopathy, and cardiac complications. Search strategies were applied to MEDLINE, EMBASE, LILACS, CENTRAL, Scopus, and Trip databases. We used a random-effects model to pool results across studies and Peto’s one-step odds ratio (OR) for event rates below 1%. Both-armed zero-event studies were excluded from the meta-analyses. We used the Grading of Recommendations Assessment, Development, and Evaluation system to evaluate the certainty of evidence. Results One hundred and six RCTs were included. We found no significant difference between CQ/HCQ and control (placebo or non-CQ/HCQ) in the frequency of SAEs (OR: 0.98, 95% confidence interval [CI]: 0.76–1.26, 33 trials, 15,942 participants, moderate certainty of evidence). However, there was a moderate certainty of evidence that CQ/HCQ increases the incidence of cardiac complications (RR: 1.62, 95% CI: 1.10–2.38, 16 trials, 9908 participants). No clear relationship was observed between CQ/HCQ and retinopathy (OR: 1.63, 95% CI: − 0.4–6.57, 5 trials, 344 participants, very low certainty of evidence). Conclusions CQ and HCQ probably do not increase SAEs, with low frequency of these adverse events on malarial and non-malarial conditions. However, they may increase cardiac complications especially in patients with COVID-19. No clear effect of their use on the incidence of retinopathy was observed.

Abstract Paracoccidioidomycosis is an endemic systemic mycosis caused by Paracoccidioides brasiliensis complex and P. lutzii. It is a rare disease in non-HIV-induced immunosuppressed individuals. In organ transplant recipients, it is more frequently associated with immunosuppression after kidney transplantation. In a liver transplant patient, only one case has been published in the literature to date. The present report comprises the case of a 47-year-old female patient with disseminated skin lesions associated with signs and symptoms of systemic involvement of paracoccidioidomycosis that manifested one year after liver transplantation and under an immunosuppression regimen with tacrolimus and mycophenolate mofetil.

Abstract The severe bacterial diseases discussed herein are those that present dermatological lesions as their initial manifestations, for which the dermatologist is often called upon to give an opinion or is even the first to examine the patient. This review focuses on those that evolve with skin necrosis during their natural history, that is, necrotizing fasciitis, Fournier gangrene, and ecthyma gangrenosum. Notice that the more descriptive terminology was adopted; each disease was individualized, rather than being referred by the generic term “necrotizing soft tissue infections”. Due to their relevance and increasing frequency, infections by methicillin-resistant Staphylococcus aureus (MRSA) were also included, more specifically abscesses, furuncle, and carbuncle, and their potential etiologies by MRSA. This article focuses on the epidemiology, clinical dermatological manifestations, methods of diagnosis, and treatment of each of the diseases mentioned.

Abstract Hemostatic and adhesive agents date back to World War II, when homologous fibrin sealant came onto scene. Considering that infectious diseases can be transmitted via human blood, a new heterologous fibrin sealant was standardized in the 1990s. Its components were a serine protease (a thrombin-like enzyme) extracted from the venom of Crotalus durissus terrificus snakes and a fibrinogen-rich cryoprecipitate extracted from the blood of Bubalus bubalis buffaloes. This new bioproduct has been used as a coagulant, sealant, adhesive and recently as a candidate scaffold for mesenchymal stem cells and bone and cartilage repair. This review discusses the composition of a new heterologous fibrin sealant, and cites published articles related to its preclinical applications aiming at repairing nervous system traumas and regenerating bone marrow. Finally, we present an innovative safety trial I/II that found the product to be a safe and clinically promising candidate for treating chronic venous ulcers. A multicenter clinical trial, phase II/III, with a larger number of participants will be performed to prove the efficacy of an innovative biopharmaceutical product derived from animal venom.

Abstract: Milker's nodule is an occupational dermatovirose caused by Parapoxvirus, which is self-limited and, due to the lack of information of health professionals, may lead to underdiagnosis. We present two cases with exuberant manifestations and classic histopathologic findings. Case 1: Male, 19 years of age, milker, presented nodules and blisters on his palm for 15 days. Case 2: Male, 33 years of age, administrative assistant, presented erythematous nodules on his palms with lymphangitis for 5 days. He had milked a cow one week before the onset of the lesions. In both cases, the histopathology was representative and coincident with the clinical hypothesis. The lesions have presented complete involution. Milker's nodule diagnosis is based on clinical presentation, epidemiology, and histopathology. The knowledge of this disease is essential for its correct diagnosis, as well as to guide the implementation of public health measures and the appropriate treatment of sick cattle.

Abstract A 57-year-old female showed bulky, loose tumors, which progressively spread to her arms, anterior chest, and back. She reported dysphagia and dyspnea after mild exertion. She denied alcohol consumption. CT scan of her chest showed no internal lesions. Benign symmetric lipomatosis is a rare syndrome, clinically described as multiple nonencapsulated lipomas of various sizes and symmetrical distribution. This syndrome has three known phenotypes; in type 2 (Launois-Bensaude syndrome), lesions occur primarily on the shoulders, upper arms, and chest, and is unrelated to alcoholism. It causes aesthetic deformities and might block the upper airways. Mediastinal invasion might occur as well.

FUNDAMENTOS: Drogas podem desencadear reações adversas. As manifestações cutâneas são as mais comuns. OBJETIVO: Analisar as farmacodermias e relacionar as drogas envolvidas e os tipos de reações cutâneas mais freqüentes. MÉTODOS: Estudo retrospectivo e descritivo. Avaliados pacientes com diagnóstico inicial de farmacodermia internados na Enfermaria de Dermatologia, no período de janeiro de 1999 a junho de 2004. Incluídos no estudo os pacientes que confirmaram o diagnóstico de farmacodermia, com base em critérios clínicos e histopatológicos, após a análise dos prontuários. RESULTADOS: Tiveram diagnóstico inicial de farmacodermia 121 pacientes. Incluídos 43 pacientes, dos quais 51,2% eram do sexo feminino, e 86% da raça branca. Destes, 48,8% faziam uso de apenas uma medicação, sendo o grupo dos antibióticos o mais utilizado (20,9%) e o principal responsável pela farmacodermia(33,3%). O segundo grupo de drogas mais envolvido foi o dos antiinflamatórios (16,7%), seguido pelo dos anticonvulsivantes (13%), e analgésicos/antipiréticos (13%). A forma clínica da erupção cutânea foi exantema maculopapular em 41,9% dos pacientes, eritrodermia em 25,6% e urticária em 23,3%. CONCLUSÃO: O exantema maculopapular foi a principal forma de reação cutânea desencadeada por drogas, e os antibióticos, os medicamentos que mais freqüentemente desencadearam essas reações.BACKGROUND: Drugs may trigger adverse reactions and skin manifestations are the most frequent ones. OBJECTIVE: To assess drug reactions and report the drugs involved and the most frequent types of skin reactions. METHODS: A retrospective and descriptive study. Data of inpatients at the Dermatology Ward with initial diagnosis of adverse drug reactions were evaluated from January 1999 to June 2004. Patients with confirmed diagnosis were included in the study based on clinical and histopathological criteria, after analysis of medical charts. RESULTS: Initial diagnosis of adverse drug reactions was confirmed in 121 patients. Forty-three patients were included in the study; 51.2% were females and 86% were caucasians. A total of 48.8% were on one drug only. Antibiotics were the most commonly used drug (20%) and accounted for 33% of the drug eruptions. The second group comprised anti-inflammatory drugs (16.7%), followed by anticonvulsants (13%), analgesic/antipyretic (13%) agents. Skin eruption manifested as maculopapular exanthema in 41.9% patients, erythrodermia in 25.6%, and urticaria in 23.3%. CONCLUSION: Maculopapular exanthema was the main type of skin reaction triggered by use of drugs, and these reactions were most frequently caused by antibiotics.

Úlceras venosas são comuns na população adulta, causando significante impacto social e econômico devido a sua natureza recorrente e ao longo tempo decorrido entre sua abertura e cicatrização. Quando não manejadas adequadamente, as úlceras venosas têm altas taxas de falha de cicatrização e recorrência. Apesar da elevada prevalência e da importância da úlcera venosa, ela é freqüentemente negligenciada e abordada de maneira inadequada. Esta revisão discute abordagem diagnóstica e terapêutica das úlceras venosas. O diagnóstico clínico baseia-se em história e exame físico, com ênfase nos sinais e sintomas associados e palpação dos pulsos dos membros inferiores. A ultra-sonografia Doppler deve ser utilizada para determinar o índice pressórico entre o tornozelo e o braço, e exames não invasivos, como o duplex scan, devem ser realizados para avaliar o sistema venoso superficial, profundo e perfurante. Para abordagem terapêutica são fundamentais os diagnósticos clínico e laboratorial corretos, além do diagnóstico e tratamento adequados das complicações das úlceras crônicas. Os esforços devem ser direcionados para a cicatrização da úlcera e, posteriormente, para evitar as recidivas. O grande avanço no conhecimento da fisiopatogenia das úlceras venosas tem permitido o desenvolvimento de novas modalidades de tratamento clínico e cirúrgico.Venous ulcers are common in adult population. They cause significant socioeconomic impact due to recurrence and the long interval between onset and healing. If venous ulcers are not appropriately managed, they present high rates of healing failure and recurrence. Despite their high prevalence and importance, venous ulcers are often neglected and inadequately managed. This review discusses diagnosis and therapy of lower limb venous ulcers. Clinical diagnosis is based on history and physical examination, emphasizing associated signs and symptoms, and pulse palpation of lower limbs. Doppler must be used to determine the ankle-arm index, and non-invasive exams, such as duplex scan, are requested to evaluate the superficial, deep and perforating venous systems. Accurate clinical and laboratory diagnosis of venous ulcers, as well as appropriate treatment of their complications are fundamental for successful therapy. Efforts must be directed towards healing and avoiding recurrences. Advanced knowledge on the venous ulcer physiopathogenesis has led to development of new clinical and surgical treatments.

CONTEXT AND OBJECTIVE: Chronic urticaria-angioedema is a common, multiple-cause complaint. The aim was to investigate the sociodemographic and clinical characteristics, causal and aggravating factors and evolution of urticaria-angioedema. DESIGN AND SETTING: This was a descriptive prospective study carried out at the Dermatology outpatient clinic of Faculdade de Medicina de Botucatu, Universidade Estadual Paulista (Unesp). METHODS: A total of 125 patients with chronic urticaria-angioedema were evaluated to obtain sociodemographic data, anamnesis, dermatological and general clinical data and laboratory data, emphasizing causal and aggravating factors and complaint evolution. RESULTS: Chronic urticaria-angioedema occurred mainly in females (mean age: 35 years), but also in men (mean age: 32 years). White color and living in urban areas also predominated. There was no preferential time for symptoms to appear, and nighttime was the most commonly reported time for clinical worsening. Around half of the patients had urticaria associated with angioedema. There were no associated factors in most of the cases, and stress was the most commonly reported aggravating factor. The cause was ascertained in 37.6% of our cases. The mean duration of follow-up was 11.7 months. Around 60% of the patients evolved with the problem under control, 32% improved, 9% had no change in dermatological condition and only one patient worsened. CONCLUSIONS: Chronic urticaria-angioedema was more common among middle-aged women. It is a long-term disease, and its cause was explained in about one-third of the patients. Half of the patients presented disease control after treatment lasting an average of approximately one year.

ABSTRACT Objectives: To compare the knowledge on surgical safety through the team-based learning methodology and lecture classes for undergraduate Nursing students, and evaluate the learning satisfaction with team-based learning. Methods: Randomized, controlled, parallel, two-arm, unblinded clinical trial developed in the Faculty of Medicine of a public university in Botucatu, Brazil. The groups included 14 students for team-based learning and 11 students for lecture classes. Results: Students’ apprehension of knowledge in the team-based learning group was significantly higher compared to the control group (p

Objective: To validate the Glamorgan Scale and compare its predictive ability in assessing pressure injury risk among patients in a pediatric ICU (PICU) with that of the Braden Q Scale., Methods: A prospective cohort study was performed to validate the Glamorgan Scale and compare its predictive ability with the Braden Q Scale in a PICU population. A total of 83 patients admitted in the PICU between February and July 2020 met the inclusion criteria and were included in the study, leading to 639 measurements. The authors tested the psychometric properties of the Glamorgan Scale to validate whether the characteristics of the original version were preserved. To this end, reliability (internal consistency) and concurrent and predictive validity (sensitivity and specificity) were assessed. For the predictive comparison, the authors performed the same tests with the Braden Q Scale., Results: The predictive validity, as assessed by the receiver operator characteristic curve and calculation of the area under the curve, showed satisfactory performance for the Glamorgan Scale (0.77; CI, 0.72-0.82); the Braden Q Scale values were similar (0.78; CI 0.73-0.84). The Spearman correlation coefficient showed a strong correlation between the total scores of the Glamorgan Scale (ρ = -0.76; P < .01), corroborating its validation., Conclusions: The Glamorgan Scale was validated and showed good accuracy and consistency for pressure injury risk assessment in critically ill pediatric patients in Brazil. Its accuracy was similar to that of the Braden Q Scale., (Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.)

Objective: Identify both the risk of developing pressure injuries (PIs) by applying the CALCULATE (CriticAL Care pressure ULcer Assessment Tool made Easy) and Braden Scales and the incidence of PIs in adult patients in intensive care., Methods: This prospective cohort study was conducted from March 2016 to February 2017 in an adult ICU. The Braden and CALCULATE scales were applied every 48 hours until medical discharge, death, or PI development., Results: The sample included 100 patients. The investigators obtained 818 evaluations (409 Braden and 409 CALCULATE) with an average of 4.1 observations per patient. According to the CALCULATE scale, 49 participants (49%) were classified as very high risk, compared with 40 participants (40%; P = .204) according to the Braden Scale. Thirty-five patients developed 37 PIs, with a total incidence of 35%. The mean age of patients who developed PIs was 60.3 (SD, 13.7) years, and they averaged 9.2 (SD, 6.8) days of hospitalization, with diagnoses related to cardiorespiratory and neurologic diseases and associated comorbidities of hypertension, diabetes mellitus, and smoking. The most affected site was the sacral region; 64.9% of the injuries were classified as stage 1., Conclusions: Patients in intensive care were high risk according to both PI scales, and many developed PIs. It is evident that even when preventive measures are used, they are insufficient without the implementation of preventive protocols., (Copyright © 2022 Wolters Kluwer Health, Inc.

Objective: To identify the risk and incidence of pressure injuries in bedridden pediatric patients to determine the most prevalent risk factors and preventive measures and to define the sociodemographic, clinical, and therapeutic profiles in this group., Methods: Prospective cohort study performed between March 2015 and March 2016 in the intensive care unit and the pediatric ward of a public teaching hospital. The study included 85 pediatric patients (45 intensive care unit and 40 pediatric ward patients)., Main Outcome Measure: Patients' Braden Q Scale score was assessed at 48-hour intervals until discharge from the aforementioned units, discharge from the hospital, and/or death., Main Results: Researchers observed that 93.3% of intensive care unit patients and 87.5% of pediatric ward patients were categorized as high-risk patients, and 12 patients presented with 24 pressure injuries with an incidence of 14.1% and a mean of 4 days before pressure injury occurrence. Patients with pressure injuries in the cohort averaged a hospital length of stay of 7.7 days. Of these, the mean age was 4.1 years and most were female, receiving enteral nutrition, and had diagnoses related to neurological and respiratory diseases.' Vasopressor use had a statistically significant association (P < .05) with the development of pressure injuries. The primary risk factor identified on the Braden Q Scale for the development pressure injury was a "mobility and activity" deficit., Conclusions: Most patients (hospitalized in either unit) were at high risk of developing pressure injuries. No specific preventive guidelines were in place in this hospital prior to this study; therefore, the authors aimed to develop a protocol for the prevention and reduction of pressure injuries in pediatric patients.

Objective: This study aimed at evaluating the flora and bacterial load of chronic leg ulcers (CLUs) according to the clinical judgment of colonization or infection., Design: This was an analytical and cross-sectional study., Setting: This study was conducted in an outpatient wound care unit in the Dermatology Department of the Botucatu School of Medicine-UNESP, Brazil., Participants: The participants were patients with CLUs who did not use systemic antibiotics., Methods: The ulcers were clinically divided into 3 groups: ulcers with good granulation tissue (GGT), critical colonization (CC), and infection. Secretion was collected from a 1-cm area using a swab and seeded by the semiquantitative method., Outcome Measures: The main outcome measures were genus and species of the bacteria found in the cultures and result of the semiquantitative culture correlating with the clinical diagnosis of GGT, CC, and infection., Main Results: Seventy-seven ulcers were evaluated: 27 with GGT, 29 with CC, and 21 with infection. Gram-negative bacteria were most often found in all groups (81%): Pseudomonas aeruginosa, in granulation and colonized ulcers, and Proteus mirabilis, in infected ulcers. Ulcers from the infected group showed higher bacterial load., Conclusions: The flora of CLUs was predominantly constituted by gram-negative bacteria, and P aeruginosa was the most prevalent. The bacterial load of infected ulcers was higher as compared with the others, although some ulcers with GGT also presented a high load. The interpretation of microbiologic tests based on the swab techniques and even on semiquantitative analysis requires close clinical correlation.
